To all 71177/0717, it may concern:

Be it known that I, ARTHUR E. WHITn,a citi- Zen oi the United States, residing at Chicago,v

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring Cots or Lounges, ot' which the following is a specification.

The invention relates to that type ot' spring cots or lounges in which the reposing part of the cot or lounge has a rising-and-'t'alling movement given thereto from springs at one end thereof.

The objects of the present invention are to construct a spring' cot or lounge with companion side trames,each side tranne having a bottom rail continuing at its 'forward end to form a coil, with a top rail rearwardly extending from the coil, the bottom rail, the coil, and the top rail being made et a single rod or bar; to furnish a form of spring connecting the bottom rail and top rail and so arranged in relation to the rails at their front ends as to allow the top rail to rise and Jfall in a uniform and easy movement; to have the top rail depart from the curvature or circle of the springcoil, so as to give an upward inclination jfor the side rail at an angle that when an occupant is on the reposing-section of the cot or lounge the resiliency of the spring-coil eX- tends for the length of its entire circle without any strain on one part more than on another part, thus insuring an easy and perfect rising-and-falling movement, and to improve generally the arrangement oi' the several parts entering into the construction of the cot or lounge as a whole.

The invention consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings, Figure I is a perspective view showingthe support formed of two companion side 'trames having a similar construction; Fig. 2, a similar view to Fig. l, showing a canvas or covering' stretched over the top rails of the side frames; and Fig. 3, a perspective view showing, a mattress on the top rails et' the side frames and a basket or receiver on the bottom rails of the side frame.

The support is formed of two companion side frames A, each side frame having a bottom rail e, which at its forward end is curved around to furnish a spring-coil d, extending rearwardly from which is a top rail a2, the rails and spring-coil being integral and formed of a single rod or bar, and the top rails preferably are of greater length than the bottom rails, so that when.the cot or lounge has an occupant thereon the weight will be sustained by the spring-coils and will be supported ou the base-rails in such manner as to give an easy rising-and-falling movement for the top rails through the resiliency of the spring coils, which resiliency extends over the entire circle et the coils by reason of the departure of the curve for the inner end of the top rails from the true circle of the body ot' the spring-coils, which departure is one that will cause the upanddown movement otl the top rails to extend continuously around the circle of the coil instead el? an increased tension at one point et' the spring-coil.

The side frames A at -the rear ends olI the bottom rails c are connected together bya cross-bar I), the ends of which are secured in legs or feet depending from a socket entered onto the end of each side rail, and when in position locked and held by a set-screw 7) or otherwise. Each leg' or 'toot 6 has journaled in its end a caster ball or wheel 7), serving as a rolling support 'for the cot or lounge. The bottom rails e at their front ends are connected together by a cross rod or bar C, the ends of which are entered into legs or feet c, depending from a socket c', adjustable on the side rail, and when adjusted locked and held in position by a set-screw c2 or otherwise. Each leg or toot c has journaled in its lower end a caster ball or wheel c3, completing the rolling support for the cot or lounge as a whole. The rear ends of the top rails ci are connected together by a cross-bar D, the ends of which are entered in bosses d, each boss extending out from a socket ball or lieadd, entered onto the end of the top rail and locked thereto by a setscrew d2 or otherwise. A cross rod or bar E is located at the forward end oi' the top rails a2, with the ends of the cross rod or bar E secured in bosses e, extending' out from sockets c', each socket secured to its top rail by a setscrew c2 or otherwise, so that the cross rod or bar E can be adjusted as required for the reception of the canvas or covering F or Vlor the attachment of a mattress G of any usual construction. The canvas F has its side edges f turned over the top rails e2 and secured by stitching or otherwise, and has its forward end f turned over the cross rod or bar E and secured by stitching or otherwise, and has its rear end f2 turned over the cross rod or bar D and secured by stitching or otherwise. The canvas is drawn taut by means ol the crossrod or bar E, and when taut the rod orv IOO IIC

bar is locked in place by the set-screws, so that the canvas or covering F will furnish a proper support for a mattress or for the occupant if a mattress is not desi red. The mattress can be mounted on the canvas or covering F, as shown by the dotted lines in Fig. 2, or the mattress can be attached direct to the top rails and the cross-bars by securing the side edges g of the mattress in any suitable manner to the side rails and securing the front end g' in any suitable manner to the cross rod or bar E and securing the rear end g2 of themattress to the cross-bar D and the rear ends of the top rails in any suitable manner. The con struction shown in Fig'. 3 has attached to the base of the support a basket H, having side walls /t and end walls L, the side walls beingsecured to the bottom rails o and the end walls being secured to the cross-bars B and C in any suitable manner.

The side frames are each formed of a bottom rail c, a spring-coil a, and a top rail c2, with the rails and spring-coil integral. The resistance to a weight supported on the top rails c2 extends through the entire circle of the spring-coils, and for this reason the occupant of the cot or lounge has a uniform and easy rising-and-falling movement without any sudden jar or concussion. The weight of the occupant counterbalances and serves as a counterpoise for the resiliency of the spring, and by the occupant adjusting himself or herselfI higher or lower on the mattress or canvas the weight of the occupant can be shifted, so as to give a perfect and reliable counterpoise against the resiliency of the springcoils, thereby giving a uniform, easy, and perfect rising-and-falling movement in use. The weight of the occupant is carried by the spring-coils, starting at the initial turn of the coils at the forward ends of the bottom rails, and the weight of the occupant is supported on the base-rails, so as to hold the cot or lounge in position in use against movement from the rise and fall of the top rails.

The two side frames are duplicates of each other, so that no time or trouble is wasted in assembling' the parts, as any two side frames can be used together with the assurance of being correct and of proper construction. The cross-bar C is slipped onto the bottom rails A and advanced to its forward position, and the cross-bar B is slipped onto the bottom rails at the rear ends thereof, and when in position the bars are secured to the bottom rails by the set-screws or other suitable means. The cross-bar E is slipped onto the top rails and advanced to its forward position and there secured by the set-screws or other suitable means, and the cross-bar D is entered onto the rear ends of the .top rails and there secured by set-screws or other suitable means. It will thus be seen that the assembling of the parts is readily and quickly accomplished, and when assembled the support as awhole is firm and unyielding except as to the free and easy rising-and-falling movement of the top rails when the cot or lounge is occupied.

The support as a whole is of simple construction, and at the same time, owing to the manner of forming the bottom rails, the spring-coil, and the top rails for the two companion side frames all from a single rod or bar for each side frame, the support is well adapted for the application of a canvas or covering or for a mattress, either of which can be readily applied to the top rails.

The cot or lounge when completed will be found very desirable, as in use the occupant will not be subjected to any jar or concussion arising' from the effects of the spring-coil, and in addition the weight of the occupant can be so adjusted in relation to the springcoils as to give a free, easy, and perfect rising-and-falling movement in use.
